Size here is decided by two things at once: how long a bottle should last, and whether the required text fits on it.

The range we hold

From about 15 ml to 120 ml. The small end is a sample or a trial, the middle is the standard retail format, and the large end suits a product taken in larger servings or sold as better value.

Match it to a sensible repurchase cycle

A bottle that lasts a month is a natural rhythm for a product people take daily, and it keeps the product fresh in use. A bottle that lasts six months is one spending most of its life part empty, with light and air working on it.

The label is a hard constraint at the small end

Everything on the panel-real-estate page lands here. Below about 30 ml the mandatory text genuinely struggles, and the answer is usually a wrap label, an extended-content label or a carton rather than smaller type.

Sampler sizes need the same text

A 15 ml trial bottle carries the same required elements as a full one, which surprises people who treat samples as marketing rather than product. That is often what makes a sampler uneconomic once the carton is counted.

Headspace and oxidation

A part-used bottle has air in it, and for a botanical extract that matters over months. It is a smaller effect than in oils and it is a reason the right size is the one that gets finished.

Cost a bottle as a bottle

A 15 ml and a 120 ml cost nearly the same to fill, label and handle, and the label may cost more on the small one. Costing from a per-milliliter figure makes the small size look better than it is.

Settle the size before the dropper

Pipette length is specified to the bottle, so changing format after ordering closures leaves you with droppers that bottom out or cannot reach. It is a cheap mistake to avoid and an expensive one to discover after a bulk order.
